Abstract (en)
A method for efficiently establishing connections along a network route, including determining a maximum capacity, determining a set of concatenation constraints and allocating selected resources along the route to allow the delivery of any combination of signals satisfying the determined set of concatenation constraints and having a total capacity not exceeding the maximum capacity. The signal make-up of the open connection can be changed as desired, without having to re-allocate the resources each time. Also disclosed is a method of establishing at least one higher layer connection within a lower layer connection, including determining a first capacity associated with the lower layer connection; determining a first set of concatenation constraints associated with the lower layer connection; establishing the lower layer connection by allocating selected resources along the route to allow the delivery of any combination of signals satisfying the first set of concatenation constraints and having a total capacity not exceeding the first capacity and, for each of the at least one higher layer connection, using a respective subset of the allocated resources to carry a respective combination of signals satisfying a respective set of second concatenation constraints which is a subset of the first set of concatenation constraints. <IMAGE>
